Abstract:Familial hypertrophic cardiomyopathy (HCM) affects .2% of the world's population and is inherited in an autosomal dominant manner. Mutations in cardiac α‐actin are the cause in 1%–5% of all observed cases. Here, we describe the recombinant production, purification, and characterization of the HCM‐linked cardiac α‐actin variants p.A21V and p.D26N. Mass spectrometric analysis of the initially purified recombinant cardiac α‐actin variants and wild‐type protein revealed improper N‐terminal processing in the Spodop… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
